BELT CONVEYER.

SPECIFICATION forming part of Letters Patent No. 756,630, dated April 5, 1904.

Application filed November 18, 1902i Serial No. 131,870. (No model.)

a longitudinal sectional view of my improved Conveyer. Fig'. 2 1s a transverse sectional view on the line 2 2, Fig. 1. Fig. 3 is a scctional view showing only one run of the belt carried by a iilm of air. Fig. 4 isa view showing the air-chamber having a'concaved upper surface. Fig. 5 is a sectional View showing deilectors for the air escaping past the edges of the belt. Fig. 6 is a modification of the device shown in Fig. 5. Fig.`7 is a view showing the edges of the belt resting' on inclined portlons of the box. Fig. 8 1s a sectional View showing the combination of the deflector with a box having the inclined portions upon which the edges of the belt rest, and Fig. 9 is a view showing the device illustrated in Fig. 8 in combination with the boX having a concaved upper surface.

A is an endless belt. which passes around wheels B at each end of the conveyer and preferably over guide-wheels D is an air-box made in the present instance to accommodate both runs of the conveyerbelt. l

D' is one air-chamber, and D2 is the other air-chamber. The air-chambers are separated by a perforated partition d, which is directly under the'return run of the belt A. The upper partition (Z, which is directlyT under the carrying run of the belt, is also perforated, as shown in Figs. 1 and 2.

The air-inlet pipes C communicate with any portion of the box D as desired. In Fig. l l have shown the inlet-pipe communicating with one end of the lower air-chamber D2.

The perforations in the partitions d zZ' may be either slots or holes of any form and may be inclined, as shown in Fig'. l, so that the air will act not only as a support or lubricant, but also as a driving' means, as the blasts of air will impinge upon the under side of the belt. and cause it to move forward. The openings may be graduated in long conveyers, and the air-box may be made in sections by placing vertical partitions therein, if desired. rhen the perforations are not inclined, then the belt must be driven from some outside means. vEither one of the wheels B may be the d riving'Y wheel of the apparatus,and in some instances the driving' may be done through one of these wheels, as well as by the air-blast.

In order to discharge the material at any point on the carrying run of the belt, 1 provide a traveling discharg'er E, which has wheels c', mounted on rails e, in the present instance on the upper edges of the sides (Z2 of the box Al and this discharger has two drum's l E2 one above thc other and around which the carrying' run of the belt passes, as shown in Fig. l. Directly in front of the upper roll is a hooded chute F in the present in# stance to receive the material as it is discharged from the belt.

Carried by the discharger E is a cover-plate 12, which rests close to the perforated partition d and closes the openings between the point that the belt leaves the partition and the point it returns to the partitions. 1n some instances the upper portion of the cover-plate may conform to the line of the belt for a certain distance, and passages c3 may be formed therein, as in Fig. l, to admit air under the belt at this point.

1t will be noticed in referring to Fig. 2 of the drawings that there is clearance between each edge of the belt and thesides of the airbox D, so as to allow for the escape of a certain proportion of air from underneath the belt.

In Fig. 5 I have shown deilectors g r/ on the sides of the box D directly above the clearance-passages, so as to deflect the air toward the load carried by the belt, and thus the escaping air tends to keep the small particles of material (if granular material is being carried) away from the edges of the belt. In Fig. 6 lhave shown deflectors g', turned IOO ' v downward over the edges of the belt, and ex- I barista-openings g2 in thc sides of the box Dto allowi'or the escape of air when itis-not' wished to have thev air escape nean the material being conveyed.- Y

vIn Fig. 3,.1 havezshown a single air-box D3 for the carrying run only of the belt A, the rcturn run of the beltbeing hung or supported at intervals in the ordinary manner.

In Fig. 4 l have illustrated a belt curved laterally on the carrying run,yth belt conforming to the curveof the partition-plate d". The return run of the belt is flat, as shown.

In some instances Athe partition-plate may be slightlybevcled at each edge, as in Fig. 7,

so that the belt will have a neat fit against the beveled edge, but will allowA air under pressure to escape. I

The operation of the conveyer is as follows: Air is admitted to the box D at the pressure desired, and the conveyer-belt is driven either by the air or driving-wheels, or both. The air passing through the perforations in the partitions d and rl will support the belt without the use of .rollers or other supports. The load will not be disturbed in Aits travel, as the belt- AWill be carried evenly over the body of air.

The air will escape at the sides of the belt in the proper proportion to allow for the correct buoying of the belt with or without its load,

and by moving the discharging device E the load can be discharged at any point desired. 1 claim as my inventionil. The combination of an endless conveying-belt, and means for supplying a film of vair to support said belt, substantially as described.

2. The combination of a conveying-belt, an

The combination of an endlessconvcying-belt, an air-box under the bel-t and communicating with the under side thereof, so that a film of air will supportthe belt in its travel, the belt being narrower than the box to form clearance-passages, substantially as described.

6. The combination of a conveyer-belt, an air-box'under the belt communicating 'with the under side thereof, so that a film of air will support the belt in its travel, the belt bcing narrower than the box so as to form clearance-passages therefor,and deectors above the clearance-passages, substantially as d escribed.' I

7 The combination of a conveyor-belt, an air-box under the belt communicating with the under side thereof, so as to support the belt in its travel, the belt being narrower than the box so as to form clearance-passages therefor, and deectors above the clearance-passages, said deectors being-,arranged at an angle so as to direct the`air over the upper surface of the belt, substantially as and for the purpose set forth.

'In testimony whereof I have signed my name to this speciiication in the presence of two subscrbing witnesses.
